Three-Way Car Catalyst Converter Saab 93 1.8i Z18XE 11/03-

The three-way catalyst converter is made up of a ceramic or metallic substrate coated with a washcoat of materials such as alumina, ceria, or zirconia. This washcoat contains precious metals such as platinum, palladium, and rhodium, which act as catalysts to promote the chemical reactions that convert harmful pollutants into less harmful substances.

As the exhaust gases flow through the catalytic converter, they pass over the catalysts, which cause the pollutants to react and break down into less harmful substances. Carbon monoxide is converted into carbon dioxide, hydrocarbons are converted into carbon dioxide and water, and nitrogen oxides are converted into nitrogen and oxygen.

Overall, the three-way catalytic converter for a Saab 93 1.8i Z18XE (11/03-) plays an important role in reducing harmful pollutants and improving air quality. It is a crucial component of the vehicle's emission control system and is required by law in most countries.
